Application: Subaru Phase-II EZ30 and EZ36 H6 – Legacy, Outback and Tribeca (see Vehicle Fitment)
Part Type: Top feed upgrade fuel rails (H6)
Part Number: 20-0765-02

Radium Engineering H6 fuel rails are a high-performance upgrade for the Subaru Phase-II EZ30 and EZ36 flat-six engines. CNC-machined from solid 6061 aluminium and black anodised and laser etched, they feature a large internal bore to support high power levels and are compatible with all fuel types including E85.

Each rail has three ports tapped for 8AN ORB fittings (six in total), and machined thermal insulating spacers provide injector height flexibility and insulate the rails from engine heat. As an upgrade rail, it retains the OEM or OEM-equivalent injectors.
